In 1977, we created the "International Series on Signal Processing and Filtering."
Our primary author is Dr. Claude S. Lindquist, well-known educator and consultant.
He is Professor Emeritus of the University of Miami.

Our books are balanced between
theory and practice. Because of this, they enjoy widespread popularity.
Our vision was to create a international series of books that focussed on signal processing
and filtering. These books would document the technology of the times and evolve as the
technology evolved. We began with active filters, then moved to digital filters, and
adaptive filters. Our philosophy was devote about half of the book to theory that was
technology independent, and the other half of the book to technology dependent designs.
This insures their long-term value.

Our books are widely acclaimed and referenced. We believe this is due primarily to the balance
between theory and practice. They continue to provide references for industrial audiences
and resources for academic teaching.
